1090MP 90 Watts, 50 Volts, Class C Avionics 1025 - 1150 MHz GENERAL DESCRIPTION CASE OUTLINE The 1090MP is a COMMON BASE bipolar transistor. It is designed for pulsed 55FW-1 systems in the frequency band 1025-1150 MHz. The device has gold thin-film metallization for proven highest MTTF. The transistor includes input prematch for broadband capability. Low thermal resistance package reduces junction temperature, extends life.
